IMO ERG mode is troublesome for sprints under 10 seconds. I can hit 800W+ pretty consistently but it takes a moment to get there. Often these work-outs just “FLIP” to a power number and when it’s lower like in this work-out I just blow right past it. It’d be nice if the spikes were more of a step (say 1 second 400W, 1 second 600W, then peak) and maybe that’s easier to do just using resistance. I’m super I’m misunderstanding something, but I’m willing to work!
